Your 12 volt battery should be about 12.5 volts without the engine running. Test and verify it is. Now with the engine running test again, Voltage should now be around 13 to 14 volts. If not, then your battery or alternator are bad. To check a battery try charging it with a battery charger.
Have you checked for a voltage draw on the battery when the key is in the off position. Also make sure the Alternator is charging.
What kind alternator is? Is Bosh or different kind?

This question really has a variant of answers. It depends on your John Deere dealer. Some will charge a restocking fee on items, especially parts, to cover the cost of returning those unused parts. Some won't charge for return parts, so you just need to contact your dealer.

It greatly depends on the machine it is mounted on. Some newer models may still be available at Deere. They will sell any available. There many versions, most with a "common" deck shell but different weldments to attach it to the machine.
